Welcome to the Purdue OWL

We're working hard to place all of our existing and brand-new material into this new version of the site. Please use the provided search box if you are having trouble finding a specific resource.

The Online Writing Lab (OWL) at Purdue University houses writing resources and instructional material, and we provide these as a free service of the Writing Lab at Purdue. Students, members of the community, and users worldwide will find information to assist with many writing projects. Teachers and trainers may use this material for in-class and out-of-class instruction.

For more information about services for the Purdue University community, including one-to-one consultations, ESL conversation groups and workshops, please visit the Writing Lab site.


The Purdue University Writing Lab and Purdue Online Writing Lab (OWL) assist clients in their development as writers—no matter what their skill level—with on-campus consultations, online participation, and community engagement. The Purdue Writing Lab serves the Purdue, West Lafayette, campus and coordinates with local literacy initiatives. The Purdue OWL offers global support through online reference materials and services.
